Binary search algorithm isn't returning variable

Question

I'm very new to binary search and I attempted a code that would read values from a document and then the user can input a number to search for from the document, and through binary search, the number would be found. I'm having trouble now because the "low" variable that I initialize in the binary search section of my code is not being returned to my main code and there's an error that says "low can not be resolved to a variable".

Here is the code for my binary search:

static public int search (int[]numbers,int target, int count)
{
    int high = numbers.length;
    int low = -1;
    int middle = (high+low)/2;
    
    while(high-low>1)
    {
        count++;
        middle = (high+low)/2;
        if(numbers[middle]>target)
        {
            high = middle;
        }
        else if(numbers[middle]<target)
        {
            low = middle;
        }
        else
        {
            break;
        }
        System.out.println(numbers[middle]);
        System.out.println(middle);
    }
        if(low == -1 || numbers[low]!=target)
        {
            low=-1;
            return low;
            
        }
        else
        {
            return low;
        }
        
        
}

And here is the code from my main code. The part with the if statements is where the error is showing up:

public static void main(String[] args) throws IOException {
    DataInputStream input = new DataInputStream(System.in);
    int [] numbers = new int [50000];
    int target;
    int count=0;
    
    try
    {
        BufferedReader br = new BufferedReader(new FileReader("randNums.txt")); 
        for(int i=0;i<50000;i++)
        {
            numbers[i]=Integer.parseInt(br.readLine());
        }
        br.close();
        
        Arrays.sort(numbers);
        
        System.out.print("Choose a number between 1-100000000 to search for: ");
        target = Integer.parseInt(input.readLine());
        
        search(numbers, target,count);
        
        if(low==-1)
        {
            System.out.println("The number was not on the list.");
        }
        else
        {
            System.out.println("The number is at position " + low);
            System.out.println("It took " + count + " comparisons to find the number.");
        }
        
        
        
    }

You have to initialize low in main:
int low=search(numbers, target,count);
